Hi Andrew,
This series of patch changes all the MPC52xx related code
to use platform bus and ppc_sys instead of OCP. It's
divided in several patches that represents "steps" in
the conversion. However the intermediate states might
not be functionnal.
Theses are against a bk clone of this morning since they
depend on some patches that are on bk but not yet in
2.6.12-rc1. I just tested and they also apply/run fine
with -mm3.
Regards,
Sylvain

Once the platform patches are in bk mainstream, I'll recreate a BK tree from there containing the fec and bestcomm. If you want fec now, just use the "old" tree, it's not that old and works fine.
